Item 5.     Other Events.

On November 18, 1996, the Company consummated a Common Stock and Warrant
Purchase Agreement (the "Purchase Agreement") with Safeguard Scientifics
(Delaware), Inc., a Delaware corporation ("SSI"), pursuant to which SSI
purchased for an aggregate consideration of $1,000,000:  (i) 1,912,000 shares
(the "Shares") of common stock of the Company, $.01 par value ("Common
Stock"); (ii) a warrant (the "First Warrant") to purchase 2,388,000 shares of
Common Stock at an exercise price of $0.65 per share; and (iii) a warrant (the
"Second Warrant") to purchase 3,071,000 shares of Common Stock at an exercise
price of $0.78 per share.  The First Warrant and the Second Warrant are
referred to hereinafter collectively as the "Warrants."  The exercise prices
of the Warrants are subject to adjustment pursuant to customary anti-dilution
provisions.

The Company intends to use proceeds from the sale of the Shares and the
Warrants for working capital and general corporate purposes.

In connection with the sale of the Shares and the Warrants, the Company
granted to SSI certain piggyback and demand registration rights with respect
to the Shares and the Common Stock underlying the Warrants.  In addition, the
Company granted to SSI a right of first refusal pursuant to which, subject to
certain conditions, in the event the Company issues, sells or exchanges any
securities, it must first offer such securities to SSI and such offer must
remain open and irrevocable for 30 days.  Such right of first refusal may only
be waived in writing and terminates at such time as SSI owns less than ten
percent (10%) of the Shares.

Pursuant to the Purchase Agreement, as long as SSI owns one percent (1%) or
more of the Company's outstanding equity securities, on a fully-diluted basis,
the Company is obligated to, among other things: (i) maintain key man life
insurance on certain key employees of the Company; (ii) permit SSI to inspect
the operations and business of the Company; and (iii) fix and maintain the
number of Directors on the Board of Directors at eight (8) members.  In
addition, the Purchase Agreement also provides that as long as SSI owns such
one percent (1%), the Company is subject to certain negative covenants,
including, among other things, restrictions on:  (i) transactions with
affiliates of the Company; (ii) certain indebtedness; and (iii) amendments to
the Company's Certificate of Incorporation and Bylaws.

In connection with the transaction, the Company entered into a voting
agreement pursuant to which each of Joseph R. Burns, Thomas J. Meaney, Wayne
E. Meyer, Frederick C. Tecce and John B. Torkelsen, each a director of the
Company (collectively, the "Management Stockholders"), agreed to vote an
aggregate of approximately 6,659,214 votes for the election of two designees
of SSI to the Board of Directors of the Company.

Also in connection with the transaction, certain of the Company's AM and FM
technology was transferred to a newly-formed company, Data Design &
Development Corporation, a Delaware corporation ("3D"), pursuant to a
Contribution Agreement.  Each of the Company, SSI and certain debtholders of
the Company (including each of the Management Stockholders) owns one-third of
the issued and outstanding capital stock of 3D.  Pursuant to a License
Agreement, 3D granted to the Company, an exclusive, world-wide, royalty-free,
perpetual right and license in and to the development and marketing of FM
technology in the United States, Canada and Mexico.  Pursuant to a Technology
License Agreement, 3D granted to AM Data Transmission Corporation, a Delaware
corporation ("AM Data"), a royalty-free, exclusive, perpetual right and
license in and to the marketing of the AM technology in the United States,
Canada and Mexico.  SSI owns 75% of the issued and outstanding capital stock
of AM Data and the Company owns 25% of such capital stock.

<PAGE>

Finally, the Company entered into a Consulting Services Agreement with AM Data
pursuant to which the Company will provide consulting services to AM Data in
consideration for a fee of $200,000 for the development of the AM technology.

MIKROS SYSTEMS CORPORATION
3490 U.S. Route 1
Princeton, NJ 08540


As of November  15, 1996


To:     Safeguard Scientifics (Delaware), Inc.
        800 The Safeguard Building
        435 Devon Park Drive
        Wayne, PA  19087


Re:  Common Stock and Warrants


Gentlemen:

MIKROS SYSTEMS CORPORATION, a Delaware corporation (the "Company"), agrees
with Safeguard Scientifics (Delaware), Inc., a Delaware corporation (the
"Purchaser"), as follows:


ARTICLE I:  PURCHASE, SALE AND TERMS OF SHARES AND WARRANTS

1.01     The Common Stock.
The Company has authorized the issuance and sale of 1,912,000 shares (the
"Common Shares") of its authorized but unissued shares of Common Stock, $0.01
par value, at a purchase price of $0.523 per Common Share to the Purchaser.


1.02     Warrants.
The Company has authorized the issuance and sale of (a) a warrant,
substantially in the form set forth as Exhibit 1.02A hereto, to the Purchaser
exercisable for 2,388,000 shares of Common Stock at an exercise price per
share, subject to adjustment as to the number of shares and exercise price as
provided therein, of $0.65 (the "$0.65 Warrant") and (b) a warrant,
substantially in the form set forth as Exhibit 1.02B hereto, to the Purchaser
exercisable for 3,071,000 shares of Common Stock at an exercise price per
share, subject to adjustment as to the number of shares of Common Stock and
exercise price as provided therein, of $0.78 per share (the "$0.7883
Warrant").  The $0.65 Warrant and $0.78 Warrant are referred to collectively
as the "Warrants."  The Company has authorized and reserved for issuance, and
shall continue to reserve for issuance, free of preemptive rights and other
similar contractual rights of stockholders, a sufficient number of its
authorized but unissued shares of Common Stock to satisfy the exercise rights
of the holders of the Warrants.  Any shares of Common Stock issuable upon the
exercise of the Warrants (and such shares when issued) are herein referred to
as the "Warrant Shares."  The Common Shares and the Warrant Shares are
referred to collectively as the "Shares" and the Common Shares and the
Warrants are referred to collectively as the "Purchased Securities."


1.03 Purchase Price and Closing.
At the Closing (as hereinafter defined), the Company shall issue and sell to
the Purchaser and, in consideration of and in express reliance upon the
representations, warranties, covenants, terms and conditions of this 

<PAGE>

Agreement, the Purchaser shall purchase the Common Shares and the Warrants. 
The aggregate purchase price of the Purchased Securities being acquired by the
Purchaser at the Closing is $1,000,000 (the "Purchase Price").  The closing of
the purchase and sale of the Purchased Securities to be acquired by the
Purchaser from the Company under this Agreement shall take place at the
offices of the Company at 10:00 a.m. on November 15, 1996, or at such other
place or at such time and date thereafter as the Purchaser and the Company may
agree (the "Closing").  At the Closing, the Company will deliver to the
Purchaser (i) a certificate or certificates for the Common Shares registered
in the Purchaser's name (or the name of its nominee) and (ii) the Warrants
against delivery of a check or checks payable to the order of the Company, or
a transfer of funds to the account of the Company by wire transfer,
representing the Purchase Price as payment in full of the purchase price of
the Purchased Securities to be acquired hereunder at the Closing.


1.04     Use of Proceeds.
The Company shall use the cash proceeds from the sale of the Purchased
Securities for working capital and general corporate purposes all as more
specifically described in Exhibit 1.04.  As set forth in Exhibit 1.04, the
Company shall promptly after the Closing use the requisite part of the
proceeds to obtain the release of the Letter of Credit, issued August 27, 1996
from PNC Bank to Bank of New York on the account of the Purchaser, in the
amount of $360,000, which Letter of Credit supports a line of credit issued by
Bank of New York to the Company.

1.05     Representations of the Purchaser.
The Purchaser represents and warrants to the Company as follows:

(a)  Investment Representations.
It is the Purchaser's present intention to acquire the Purchased Securities
for its own account (and that it will be the sole beneficial owner thereof)
and such Purchased Securities are being and will be acquired by it for the
purpose of investment and not with a view to distribution or resale thereof
except pursuant to registration under the Securities Act or an exemption
therefrom, provided that Purchaser may transfer without consideration up to
15% of the Purchased Securities to certain directors, officers, and key
employees of Safeguard Scientifics, Inc. ("SSI") under SSI's Long Term
Incentive Plan subject to restrictions and other terms and conditions
substantially similar to those set forth in Exhibit 1.05(a) hereto (the "LTIP
Transfers").  The acquisition by the Purchaser of any of the Purchased
Securities acquired by it shall constitute a confirmation of this
representation by the Purchaser.  The Purchaser further acknowledges that it
understands, until registered under the Securities Act or transferred pursuant
to the provisions of Rule 144 or Rule 144A as promulgated by the Commission,
all certificates evidencing any of the Purchased Securities, whether upon
initial issuance or upon any transfer thereof, shall bear a legend,
prominently stamped or printed thereon, reading substantially as follows:

"The securities represented by this certificate have not been registered under
the Securities Act of 1933, as amended (the "Act"), or applicable state
securities laws.  These securities have been acquired for investment and not
with a view to distribution or resale.  These securities may not be offered
for sale, sold, delivered after sale, transferred, pledged or hypothecated in
the absence of an effective registration statement covering such shares under
the Act and any applicable state securities laws, or the availability, in the
opinion of counsel satisfactory to the Company, of an exemption from
registration thereunder."





<PAGE>

(b)     Access to Information.
The Purchaser or its designated representative during the course of this
transaction, and prior to the purchase of the Purchased Securities, has had
the opportunity to ask questions of and receive answers from management of the
Company concerning the terms and conditions of the offering of the Purchased
Securities and the additional information, documents, records and books
relative to the Company's business, assets, properties, Intellectual Property
Rights, condition (financial or otherwise), results of operation and
prospects.


(c)     General Access.
The Purchaser or its designated representative has received and read or
reviewed, and is familiar with, this Agreement and the other agreements
executed or delivered herewith, and confirms that all documents, records and
books pertaining to the Purchaser's investment in the Company and requested by
the Purchaser or its designated representative have been made available or
delivered to it.


(d)     Sophistication and Knowledge.
The Purchaser or its designated representative has such knowledge and
experience in financial and business matters that it is capable of evaluating
the merits and risks of the purchase of the Purchased Securities. The
Purchaser can bear the economic risks of this investment and can afford a
complete loss of its investment.


(e)     Transfer Restrictions Imposed by Securities Laws.  
The Purchaser understands that the Purchased Securities have not been
registered under the Securities Act or any applicable state securities laws,
and, therefore, cannot be resold unless they are subsequently registered under
the Securities Act and applicable state securities laws or unless exemptions
from such registration is available; except with respect of the LTIP Transfers
the Purchaser is and must be purchasing the Purchased Securities for
investment for the account of such Purchaser and not for the account or
benefit of others, and not with any present view toward resale or other
distribution thereof.  The Purchaser acknowledges that it may not resell or
otherwise dispose of all or any part of the Purchased Securities purchased by
it, except as permitted by law, including, without limitation, any regulations
under the Securities Act and applicable state securities laws; the Company
does not have any present intention and is under no obligation to register the
Purchased Securities under the Securities Act and applicable state securities
laws, except as provided in Article V hereof; and Rule 144 or Rule 144A under
the Securities Act may not be available as a basis for exemption from
registration of the Common Shares thereunder.


(f)     Lack of Liquidity.     
The Purchaser has no present need for liquidity in connection with its
purchase of the Common Shares.


(g)     Suitability and Investment Objectives.

The purchase of the Purchased Securities by the Purchaser is consistent with
its general investment objectives. The Purchaser's knowledge and experience in
financial and business matters are such that it is capable of evaluating the
merits and risks of its purchase of the Purchased Securities. 




<PAGE>

(h)     Accredited Investor Status.  
The Purchaser is an "Accredited Investor" as that term is defined in Rule 501
of Regulation D promulgated under the Securities Act.  In addition, the
Purchaser is an "institutional investor" as such term is defined in the
regulations promulgated under the Pennsylvania Securities Act of 1971.


(i)     Brokers or Finders.  
No Person has or will have, as a result of the transactions contemplated by
this Agreement, any right, interest or valid claim against or upon the Company
for any commission, fee or other compensation of any type as a finder or
broker because of any act or omission by the Purchaser or its agents.




ARTICLE II:  CONDITIONS TO PURCHASER'S OBLIGATIONS

The obligation of the Purchaser to purchase and pay for the Purchased

The Company is a duly organized and validly existing corporation in good
standing under the laws of the State of Delaware and has all requisite
corporate power and authority for the ownership and operation of its
properties and for the carrying on of its business as now conducted and as now
proposed to be conducted.  The Company is duly licensed or qualified and in
good standing as a foreign corporation authorized to do business in all
jurisdictions wherein the character of the property owned or leased or the
nature of the activities conducted by it makes such licensing or qualification
necessary, except where the failure to be so licensed or qualified would not
have a material adverse effect on the business, assets, properties,
Intellectual Property Rights, condition (financial or otherwise), results of
operation or prospects of the Company (a "Material Adverse Effect").


3.02 Corporate Action.
The Company has all necessary corporate power and has taken all corporate
action required to enter into and perform this Agreement and any other
agreements and instruments executed in connection herewith.  This Agreement,
the Voting Agreement and any other agreements and instruments executed by the
Company in connection herewith have been duly authorized, executed and
delivered by the Company and constitute the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms.  When executed and delivered by the parties at or
prior to the Closing, the Voting Agreement will have been duly authorized,
executed and delivered by the Stockholders (as defined therein) and will
constitute the legal, valid and binding obligations of such Stockholders,
enforceable against the several Stockholders in accordance with its terms. 
The Purchased Securities have been duly authorized.  The issuance, sale and
delivery of the Purchased Securities and the issuance and delivery of the
Warrant Shares upon the exercise of the Warrants have been duly authorized by
all required corporate action; the Common Shares, upon issuance in accordance
with the terms hereof, will have been validly issued, fully paid and
nonassessable with no personal liability attaching to the ownership thereof
and will be free and clear of all liens, charges, restrictions, claims and
encumbrances imposed by or through the Company except for any set forth in
this Agreement or the Voting Agreement; the Warrants, upon issuance in
accordance with the terms hereof, will have been validly issued, fully paid
and nonassessable with no personal liability attaching to the ownership
thereof and will be free and clear of all liens, charges, restrictions, claims
and encumbrances imposed by or through the Company except as set forth in this
Agreement or the Voting Agreement; and, as of the Closing, the Warrant Shares
have been duly authorized and reserved for issuance upon exercise of the
Warrants and, when so issued (assuming payment therefor has been made in
accordance with the terms of the Warrants), will be duly authorized, validly
issued, fully paid and nonassessable shares of Common Stock with no personal
liability attached to the ownership thereof and will be free and clear of all
liens, charges, restriction, claims and encumbrances imposed by or through the
Company except as set forth in this Agreement or the Voting Agreement. 
Neither the issuance, sale or delivery of the Common Shares, Warrants or
Warrant Shares is subject to any preemptive right of stockholders of the
Company or to any right of first refusal or other right in favor of any
person.

<PAGE>

3.03     Governmental Approvals.
Except as set forth in Exhibit 3.03 and except for the filing of any notice
prior or subsequent to the Closing that may be required under applicable state
and/or federal securities laws (which, if required, has been or shall be filed
on a timely basis), and no authorization, consent, approval, license,
exemption of or filing or registration with any court or governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, is or will be necessary for, or in connection with, the execution and
delivery by the Company of this Agreement, for the offer, issue, sale,
execution or delivery of the Common Shares, the Warrants or the Warrant
Shares, or for the performance by the Company of its obligations under this
Agreement or the Voting Agreement.


3.04     Litigation.
Except as disclosed in Exhibit 3.04, (i) there is no litigation or
governmental proceeding or investigation pending or, to the knowledge of the
Company, threatened against the Company affecting any of its properties or
assets, or against any officer, Key Employee or the holder of more than 10% of
the capital stock of the Company and relating to the Company or its business,
and (ii) no event has occurred and no condition exists, in each case, which
might serve as the basis on which any litigation, proceeding or investigation
might properly be instituted.  Neither the Company nor, to the best knowledge
of the Company, any officer, Key Employee or holder of more than 10% of the
capital stock of the Company is in default with respect to any order, writ,
injunction, decree, ruling or decision of any court, commission, board or
other government agency, which such default might result in a Material Adverse
Effect.  There are no actions or proceedings pending or, to the Company's
knowledge, threatened (or any basis therefor known to the Company) which
might, either in any case or in the aggregate, have a Material Adverse Effect,
or which might call into question the validity of this Agreement, the Common
Shares, the Warrants or any action taken or to be taken pursuant hereto or
thereto.  The foregoing sentences include, without limiting their generality,
actions pending or, to the Company's knowledge, threatened (or any basis
therefor known to the Company) involving the prior employment or engagement of
any of the Company's officers, employees or consultants or their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers or to any other Person. 
Without limitation to the foregoing representations, a brief summary of the
Company's material litigation and the disposition of such matters is set forth
in Exhibit 3.04.


3.05     Certain Agreements of Officers and Employees.  

(a)  No officer, employee or consultant of the Company is, or is now, to the
Company's knowledge, expected to be, in violation of any term of any
employment contract, patent disclosure agreement, proprietary information
agreement, noncompetition agreement, nonsolicitation agreement,
confidentiality agreement, or any other similar contract or agreement or any
restrictive covenant, including those set forth in Exhibit 3.21, relating to
the right of any such officer, employee or consultant to be employed or
engaged by the Company because of the nature of the business conducted or to
be conducted by the Company or relating to the use of trade secrets or
proprietary information of others, and to the Company's best knowledge and
belief, the continued employment or engagement of the Company's officers,
employees or consultants does not subject the Company or the Purchaser to any
liability with respect to any of the foregoing matters.

(b)  No officer, consultant or Key Employee of the Company whose termination,
either individually or in the aggregate, could have an adverse effect on the
Company, has terminated as of the date hereof, or, to the best knowledge of 

<PAGE>

the Company, has any present intention of terminating, his employment or
engagement with the Company.


3.06     Compliance with Other Instruments.  
The Company is in compliance in all respects with the terms and provisions of
this Agreement and of its Certificate of Incorporation and By-laws, each as
amended or restated to date, and in all respects with the material terms and
provisions of all mortgages, indentures, leases, agreements and other
instruments by which it is bound or to which it or any of its properties or
assets are subject.  The Company is in compliance in all material respects
with all judgments, decrees, governmental orders, laws, statutes, rules or
regulations by which it is bound or to which it or any of its properties or
assets are subject.  Neither the execution and delivery of this Agreement, the
Voting Agreement or the Purchased Securities, nor the consummation of any
transaction contemplated herein or therein, has constituted or resulted in or
will constitute or result in a default or violation of any term or provision
of any of the foregoing documents, instruments, judgments, agreements,
decrees, orders, statutes, rules and regulations.  A schedule of Indebtedness
of the Company as of September 30, 1996, (including lease obligations required
to be capitalized in accordance with applicable Statements of Financial
Accounting Standards) is attached as Exhibit 3.06.


3.07     Title to Assets, Patents.  
The Company has good and marketable title in fee to such of its fixed assets
as are real property, and good and marketable title to all of its assets now
carried on its books, which assets consist of those reflected in the most
recent balance sheet of the Company included as part of Exhibit 3.08 attached
hereto, or acquired since the date of such balance sheet (except personal
property disposed of since said date in the ordinary course of business), free
of any mortgages, pledges, charges, liens, security interests or other
encumbrances (collectively, "Encumbrances") other than (a) any such
Encumbrance created in accordance with the terms of the leases, security
agreements and other financing documents listed in Exhibit 3.07, (b) liens for
taxes not yet due and payable, (c) liens imposed by law and incurred in the
ordinary course of business for obligations not yet due and payable to
landlords, carriers, warehousemen, materialmen and the like, and (d)
unperfected purchase money security interests existing in the ordinary course
of business without the execution of a separate security agreement.  The
Company enjoys peaceful and undisturbed possession under all leases under
which it is operating, and all said leases are valid and subsisting and in
full force and effect.

The Company owns or has a valid right to use the Intellectual Property Rights
being used to conduct its business as now operated and as now proposed to be
operated as set forth in the 1996 Business Plan (a complete list of licenses
and registrations of such Intellectual Property Rights is attached hereto as
Exhibit 3.07); and, to the best knowledge of the Company, the conduct of its
business as now operated and as now proposed to be operated as set forth in
the 1996 Business Plan does not and will not conflict with or infringe upon
the intellectual property rights of others.  Except as set forth in Exhibit
3.07, no claim is pending or threatened against the Company or its officers,
employees and consultants to the effect that any such Intellectual Property
Right owned or licensed by the Company, or which the Company otherwise has the
right to use, is invalid or unenforceable by the Company.  Except pursuant to
the terms of any licenses specified in Exhibit 3.07, the Company has no
obligation to compensate any Person for the use of any such Intellectual
Property Rights and, the Company has not granted any Person any license or
other right to use any of the Intellectual Property Rights of the Company,
whether requiring payment of royalties or not.


<PAGE>

The Company has taken all reasonable measures to protect and preserve the
security, confidentiality and value of its Intellectual Property Rights,
including its trade secrets and other confidential information.  All employees
and consultants of the Company involved in the design, review, evaluation or
development of products or Intellectual Property Rights have executed
nondisclosure and assignment of inventions agreements sufficient to protect
the confidentiality and value of the Company's Intellectual Property Rights
and to vest in the Company exclusive ownership of such Intellectual Property
Rights.  To the best knowledge of the Company, all trade secrets and other
confidential information of the Company are presently valid and protectable
and are not part of the public domain or knowledge, nor, to the best knowledge
of the Company, have they been used by, divulged to or appropriated for the
benefit of any Person other than the Company or otherwise to the detriment of
the Company.  To the best of the Company's knowledge, no employee or
consultant of the Company has used any trade secrets or other confidential
information of any other person in the course of their work for the Company. 
The Company is the exclusive owner of all right, title and interest in its
Intellectual Property Rights as purported to be owned by the Company, and such
Intellectual Property Rights are valid and in full force and effect.  Neither
the Company nor any of its employees or consultants has received notice of,
and to the best of the Company's knowledge, there are no claims that the
Company's Intellectual Property Rights or the use or ownership thereof by the
Company infringes, violates or conflicts with any such right of any third
party.  No university, hospital, government agency (whether federal or state)
or other organization which sponsored research and development conducted by
the Company has any claim of right to or ownership of or other encumbrance
upon the Intellectual Property Rights of the Company.


3.08     Financial Information.  
The financial statements of the Company, including (i) the Company's unaudited
financial statements consisting of a balance sheet of the Company as of
December 31, 1993, 1994 and 1995 and the related statements of income,
retained earnings and cash flows for the years then ended and (ii) the
Company's unaudited balance sheet and the related statements of income and
cash flows as of September 30, 1996, all as attached hereto as Exhibit 3.08
are true and correct and present fairly the financial position of the Company
as at the dates thereof and the results of its operations for the years and
period then ended and have been prepared in accordance with generally accepted
accounting principles consistently applied, except, in the case of the
September 30, 1996 financial statements, for the absence of footnotes and
normal nonmaterial year-end adjustments.  Such financial statements are
collectively referred to herein as the "Financial Statements."  The Company
does not have, and has no reasonable grounds to know of, any liability,
contingent or otherwise, not adequately reflected in or reserved against in
the Financial Statements.  Since September 30, 1996, (i) there has been no
material adverse change in the business, assets, properties, Intellectual
Property Rights, condition (financial or otherwise), results of operation or
prospects of the Company; (ii) none of the business, assets, properties,
Intellectual Property Rights, condition (financial or otherwise), results of
operation or prospects of the Company has been materially adversely affected
as the result of any legislative or regulatory change, any revocation or
change in any franchise, permit, license or right to do business, or any other
event or occurrence, whether or not insured against; and (iii) the Company has
not entered into any material transaction other than in the ordinary course of
business, made any distribution on its capital stock, or redeemed or
repurchased any of its capital stock.  Except as set forth in Exhibit 3.08,
the Company has no liabilities or obligations of any type or nature (whether
known or unknown, matured or not, contingent or accrued) except for current
liabilities incurred in the ordinary course of business since September 30,
1996.  Also included in Exhibit 3.08 is a true, correct and complete copy of
the Company's 1996 Business Plan (the "1996 Business Plan").

<PAGE>

3.09     Taxes.  
The Company has accurately prepared and timely filed all federal, state and
other tax returns required by law to be filed by it, has paid or made
provision for the payment of all taxes due or shown to be due (including,
without limitation, the payment of all payroll and withholding taxes) and all
additional assessments, and adequate provisions have been made and are
reflected in the Company's financial statements for all current taxes and
other tax-related charges to which the Company is subject and which are not
currently due and payable.  None of the federal income tax returns of the
Company have been audited by the Internal Revenue Service (the "IRS") and the
Company is not aware of any pending or threatened audit of its Federal income
tax returns by the IRS. The Company knows of no additional assessments,
adjustments or contingent tax liability (whether federal or state) pending or
threatened for any period, nor of any basis for any such assessment,
adjustment or contingency.  Neither the Company nor, to the best of the
Company's knowledge, any of its stockholders, has ever filed a consent
pertaining to the Company pursuant to Section 341(f) of the Code relating to
collapsible corporations.


3.10     ERISA.

violation thereof; (iii) the Company and any Affiliated Company are in
compliance in all material respects with the requirements (including reporting

1986, as amended (the "Code"); (iv) neither the Company nor any Affiliated
Company or any other "disqualified person" or "party in interest" (as defined
in Section 4975 of the Code and Section 3(14) of ERISA, respectively) has
engaged in any "prohibited transaction," as such term is defined in Section
4975 of the Code or Section 406 of ERISA, which could subject any Employee
Benefit Plan (or its related trust), the Company or any Affiliated Company,
Purchaser, any shareholder, officer, director, partner or employee of the
Company, any Affiliated Company or Purchaser, or any trustee, administrator or
other fiduciary of any Employee Benefit Plan to the tax or penalty imposed
under Section 4975 of the Code or Section 502(i) of ERISA; and (v) there are
no material actions, suits or claims pending (other than routine claims for
benefits) or, to the best of the Company's knowledge, threatened, against any
Employee Benefit Plan or against the assets of any Employee Benefit Plan.  For
purposes of this Section 3.10, "Affiliated Company" shall mean any member
(whether or not incorporated) of a group which is part of a controlled group
of corporations or under common control (within the meaning of the regulations
promulgated under Section 414 of the Code) and of which the Company is a
member.  The Company does not maintain or participate in, and has never 

<PAGE>

maintained or participated in, any "multiemployer plans" as defined in Section
3(37) of ERISA.


3.11     Transactions with Affiliates.  
Except as set forth in Exhibit 3.11, there are no loans, leases, royalty
agreements or other continuing transactions between (a) the Company or any of
its customers or suppliers, and (b) any officer, employee, consultant or
director of the Company or any Person owning five percent or more of the
capital stock of the Company or any member of the immediate family of such
officer, employee, consultant, director or stockholder or any corporation or
other entity controlled by such officer, employee, consultant, director or
stockholder, or a member of the immediate family of such officer, employee,
consultant, director or stockholder.


3.12     Assumptions or Guaranties of Indebtedness of Other Persons.
The Company has not assumed, guaranteed, endorsed or otherwise become directly
or contingently liable on (including, without limitation, liability by way of
agreement, contingent or otherwise, to purchase, to provide funds for payment,
to supply funds to or otherwise invest in the debtor or otherwise to assure
the creditor against loss), any Indebtedness of any other Person except as set
forth in Exhibit 3.12.


3.13     Investments in Other Persons.
Except as set forth in Exhibit 3.13, the Company has not made any loans or
advances to any Person which is outstanding on the date of this Agreement in

The Company has complied and will comply with all applicable federal and state
securities laws in connection with the offer, issuance and sale of the
Purchased Securities hereunder.  Neither the Company nor anyone acting on its
behalf has or will sell, offer to sell or solicit offers to buy the Purchased
Securities or similar securities to, or solicit offers with respect thereto
from, or enter into any preliminary conversations or negotiations relating
thereto with, any Person, so as to bring the issuance and sale of the
Purchased Securities under the registration provisions of the Securities Act
and applicable state securities laws.


3.15     Disclosure.
Neither this Agreement, the Financial Statements, nor any other agreement,
document, certificate, statement, whether oral or written, furnished to the
Purchaser or its counsel by or on behalf of the Company in connection with the
transactions contemplated hereby contains any untrue statement of a material
fact or omits to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances in which
made, not misleading.  Projections made in the 1996 Business Plan are not
considered to be facts for the purpose of this Section.  Such projections were
prepared in good faith on the basis of reasonable assumptions, and all such
assumptions which are material to such projections have been disclosed in the
1996 Business Plan.  There is no fact within the knowledge of the Company or
any of its executive officers which has not been disclosed herein or in
writing by them to the Purchaser and which materially adversely affects, or in
the future in their opinion may, insofar as they can now foresee, have a 

<PAGE>

Material Adverse Effect.  Without limiting the foregoing, the Company has no
knowledge that there exists, or there is pending or planned, any patent,
invention, device, application or principle or any statute, rule, law,
regulation, standard or code which would have a Material Adverse Effect.


3.16     Brokers or Finders.
No Person has or will have, as a result of the transactions contemplated by
this Agreement, any right, interest or valid claim against or upon the Company
for any commission, fee or other compensation as a finder or broker because of
any act or omission by the Company or its respective agents.


3.17     Capitalization; Status of Capital Stock.
The authorized capital stock of the Company constitutes  25,000,000 shares of

list of the capital stock of the Company which has been previously issued and
the names in which such capital stock is registered on the stock transfer book
of the Company is set forth in Exhibit 3.17 hereto.  All of the outstanding
shares of capital stock of the Company have been duly authorized, and are
validly issued, fully-paid and nonassessable.  The Common Shares, when issued
and delivered in accordance with the terms hereof, will be duly authorized,
validly issued, fully-paid and non-assessable.  The Warrants, when issued and
delivered in accordance with the terms hereof, and the Warrant Shares, when
issued and delivered upon exercise of the Warrants in accordance with the
terms thereof, will be duly authorized, validly issued, fully paid and
nonassessable.  Except for (i) 3,576,666 shares of Common Stock that have been
reserved for issuance upon the exercise of outstanding stock options and
warrants as further set forth on Exhibit 3.17, no options, warrants,
subscriptions or other purchase rights of any nature to acquire from the
Company, or commitments of the Company to issue, shares of capital stock or
other securities are authorized, issued or outstanding, nor is the Company
obligated in any other manner to issue shares or rights to acquire any of its
capital stock or other securities except as contemplated by this Agreement. 
No anti-dilution adjustment has occurred or will occur as a result of the
issuance of the Warrants or the issuance of the Warrant Shares upon the
exercise of the Warrants under any outstanding warrants, the Company and the
warrant holders having amended the warrants to provide an exception for the
issuance of the Warrants and the issuance of the Warrant Shares upon the
exercise thereof.  None of the Company's outstanding securities or authorized
capital stock or the Common Shares are subject to any rights of redemption,
repurchase, rights of first refusal, preemptive rights or other similar
rights, whether contractual, statutory or otherwise, for the benefit of the
Company, any stockholder or any other Person, except pursuant hereto
(including pursuant to Exhibits 2.02(a)(i) and 3.17 hereto) or the Voting
Agreement.  Except as set forth in Exhibit 3.17, there are no restrictions on
the transfer of any shares of capital stock of the Company other than those
imposed by relevant federal and state securities laws and as otherwise
contemplated by this Agreement or the Voting Agreement.  Except as set forth
in Exhibit 3.17 or in the Voting Agreement, there are no agreements,
understandings, trusts or other collaborative arrangements or understandings
concerning the voting or transfer of the capital stock of the Company.  The
offer and sale of all capital stock and other securities of the Company issued
before the Closing complied with or were exempt from all applicable Federal
and state securities laws and no stockholder has a right of rescission or
damages with respect thereto.


<PAGE>

3.18     Registration Rights.
Except for those registration rights set forth in Exhibit 3.18, and except for
the rights granted hereunder, no Person has demand or other rights to cause
the Company to register any securities of the Company under the Securities Act
or to participate in any registration of the Company's securities under such
Act.


3.19     Insurance.
The Company carries insurance covering its properties and business which is
adequate and customary for the type and scope of its properties, assets and
business, and similar to companies of comparable size and condition similarly
situated in the same industry in which the Company operates, but in any event
in amounts sufficient to prevent the Company from becoming a co-insurer or
self-insurer, with provision for reasonable deductibles.


3.20     Books and Records.
The books of account, ledgers, order books, records and documents of the
Company accurately and completely reflect all material information relating to

ARTICLE V:  REGISTRATION RIGHTS

5.01     Piggy-Back Registrations.  
If at any time the Company shall determine to register for its own account or
the account of others under the Securities Act (including pursuant to a demand
for registration of any stockholder of the Company other than the Purchaser
exercising registration rights with respect to the Common Shares) any of its
equity securities, other than on Form S-8 or Form S-4 or their then
equivalents relating to shares of Common Stock to be issued solely in
connection with any acquisition of any entity or business or shares of Common
Stock issuable in connection with stock option or other employee benefit
plans, it shall send to each holder of Registrable Shares, including each
holder who has the right to acquire Registrable Shares, written notice of such
determination and, if within 15 days after receipt of such notice, such holder
shall so request in writing, the Company shall use its best efforts to include
in such registration statement all or any part of the Registrable Shares such
holder requests to be registered, except that if, in connection with any
offering involving an underwriting of Common Stock to be issued by the
Company, the managing underwriter shall impose a limitation on the number of
shares of such Common Stock which may be included in the registration
statement because, in its judgment, such limitation is necessary to effect an
orderly public distribution, then the Company shall be obligated to include in
such registration statement only such limited portion of the Registrable
Shares with respect to which such holder has requested inclusion hereunder;
provided, however, that the Company shall not so exclude any Registrable
Shares unless it has first excluded any securities to be offered and sold by
employees of the Company or by holders who do not have contractual, incidental
rights to include such securities (collectively, "Excludable Shares");
provided further that as between the Company and holders of Registrable
Shares, in no event shall the Registrable Shares included in such offering be
limited to less than 25% of the aggregate number of shares offered.  Any
exclusion of Registrable Shares shall be made pro rata among the persons
seeking to include such shares, in proportion to the number of such shares
owned by such persons.  No incidental right under this Section 5.01 shall be
construed to limit any registration required under Section 5.02. The
obligations of the Company under this Section 5.01 may be waived at any time
upon the written consent of holders of 60% of the outstanding Registrable
Securities.


5.02     Required Registration.  
If on any occasion one or more holders of at least 60% of the outstanding
Common Shares shall notify the Company in writing that it or they intend to
offer or cause to be offered for public sale at least 20% of the Registrable
Shares (or any lesser percentage of the Registrable Shares if the anticipated
aggregate offering price thereof would exceed $2,000,000), the Company will 

<PAGE>

notify all holders of Registrable Shares, including all holders who have a
right to acquire Registrable Shares.  Upon written request of any holder given
within 15 days after the receipt by such holder from the Company of such
notification, the Company will use its best efforts to cause such of the
Registrable Shares as may be requested by any holder thereof (including the
holder or holders giving the initial notice of intent to offer) to be
registered under the Securities Act as expeditiously as possible.  The Company
shall not be required to effect more than two such registrations in the
aggregate.  If the Company determines to include shares to be sold by it or by
other selling stockholders in any registration request pursuant to this
Section 5.02, such registration shall be deemed to have been a "piggy-back"
registration under Section 5.01, and not a "demand" registration under this
Section 5.02 if the holders of Registrable Shares are unable to include in any
such registration statement at least 85% of the Registrable Shares initially
requested for inclusion in such registration statement.


5.03     Registrations on Form S-3.
In addition to the rights provided the holder of Registrable Shares in
Sections 5.01 and 5.02 above, if the registration of Registrable Shares under
the Securities Act can be effected on Form S-3 (or any similar form
promulgated by the Commission), then upon the written request of one or more
holders of at least 60% of the outstanding Registrable Shares, the Company
will so notify each holder of Registrable Shares, including each holder who
has a right to acquire Registrable Shares, and then will, as expeditiously as
possible, use its best efforts to effect qualification and registration under
the Securities Act on Form S-3 of all or such portion of the Registrable
Shares as the holder or holders shall specify; provided, however, the Company
shall not be required to effect a registration pursuant to this Section 5.03
unless the market value of the Registrable Shares to be sold in any such
registration shall be estimated to be at least $500,000 at the time of filing
such registration statement, and further provided that the Company shall not
be required to effect more than one registration during any 12-month period
pursuant to this Section 5.03.


5.04     Effectiveness.  
The Company will use its best efforts to maintain the effectiveness for up to
90 days (or such shorter period of time as the underwriters need to complete
the distribution of the registered offering, or one year in the case of a
"shelf" registration statement on Form S-3) of any registration statement
pursuant to which any of the Registrable Shares are being offered, and from
time to time will amend or supplement such registration statement and the
prospectus contained therein to the extent necessary to comply with the
Securities Act and any applicable state securities statute or regulation.  The
Company will also provide each holder of Registrable Shares with as many
copies of the prospectus contained in any such registration statement as it
may reasonably request.


5.05     Indemnification of Holder of Registrable Shares.
In the event that the Company registers any of the Registrable Shares under
the Securities Act, the Company will indemnify and hold harmless each holder
and each underwriter of the Registrable Shares (including their officers,
directors, affiliates and partners) so registered (including any broker or
dealer through whom such shares may be sold) and each Person, if any, who
controls such holder or any such underwriter within the meaning of Section 15
of the Securities Act from and against any and all losses, claims, damages,
expenses or liabilities, joint or several, to which they or any of them become
subject under the Securities Act, applicable state securities laws or under
any other statute or at common law or otherwise, as incurred, and, except as
hereinafter provided, will reimburse each such holder, each such underwriter 

<PAGE>

and each such controlling Person, if any, for any legal or other expenses
reasonably incurred by them or any of them in connection with investigating or
defending any actions whether or not resulting in any liability, as incurred,
insofar as such losses, claims, damages, expenses, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement, in any
preliminary or amended preliminary prospectus or in the final prospectus (or
the registration statement or prospectus as from time to time amended or
supplemented by the Company) or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated
therein or necessary in order to make the statements therein not misleading,
or any violation by the Company of any rule or regulation promulgated under
the Securities Act or any state securities laws applicable to the Company and
relating to action or inaction required of the Company in connection with such
registration, unless (i) such untrue statement or alleged untrue statement or
omission or alleged omission was made in such registration statement,
preliminary or amended preliminary prospectus or formal prospectus in reliance
upon and in conformity with information furnished in writing to the Company in
connection therewith by any such holder of Registrable Shares (in the case of
indemnification of such holder), any such underwriter (in the case of
indemnification of such underwriter) or any such controlling Person (in the
case of indemnification of such controlling person) expressly for use therein,
or unless (ii) in the case of a sale directly by such holder of Registrable
Shares (including a sale of such Registrable Shares through any underwriter
retained by such holder of Registrable Shares to engage in a distribution
solely on behalf of such holder of Registrable Shares), such untrue statement
or alleged untrue statement or omission or alleged omission was contained in a
preliminary prospectus and corrected in a final or amended prospectus copies
of which were delivered to such holder of Registrable Shares or such
underwriter on a timely basis, and such holder of Registrable Shares failed to
deliver a copy of the final or amended prospectus at or prior to the
confirmation for the sale of the Registrable Shares to the person asserting
any such loss, claim, damage or liability in any case where such delivery is
required by the Securities Act.

Promptly after receipt by any holder of Registrable Shares, any underwriter or
any controlling Person of notice of the commencement of any action in respect
of which indemnity may be sought against the Company, such holder of
Registrable Shares, or such underwriter or such controlling person, as the
case may be, will notify the Company in writing of the commencement thereof
(provided, that failure to so notify the Company shall not relieve the Company
from any liability it may have hereunder) and, subject to the provisions
hereinafter stated, the Company shall be entitled to assume the defense of
such action (including the employment of counsel, who shall be counsel
reasonably satisfactory to such holder of Registrable Shares, such underwriter
or such controlling Person, as the case may be), and the payment of expenses
insofar as such action shall relate to any alleged liability in respect of
which indemnity may be sought against the Company.

Such holder of Registrable Shares, any such underwriter or any such
controlling Person shall have the right to employ separate counsel in any such
action and to participate in the defense thereof but the fees and expenses of
such counsel subsequent to any assumption of the defense by the Company shall
not be at the expense of the Company unless the employment of such counsel has
been specifically authorized in writing by the Company.  The Company shall not
be liable to indemnify any Person for any settlement of any such action
effected without the Company's written consent.  The Company shall not, except
with the approval of each party being indemnified under this Section 5.05,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or
plaintiff to the parties being so indemnified of a release from all liability
in respect to such claim or litigation.

<PAGE>

In order to provide for just and equitable contribution to joint liability
under the Securities Act in any case in which any holder of Registrable Shares
exercising rights under this Article V, any underwriter, or any controlling
Person of any such holder or underwriter, makes a claim for indemnification
pursuant to this Section 5.05 but it is judicially determined (by the entry of
a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 5.05 provides for indemnification in such case, then, the
Company, on the one hand, and such holder, underwriter or controlling Person,
on the other hand, will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from others) in
such proportion as is appropriate to reflect the relative fault of the Company
on the one hand and of the holder of Registrable Shares, underwriter or
controlling Person on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations.  The relative fault of the Company on
the one hand and of the holder of Registrable Shares, underwriter or
controlling Person on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or by the holder of
Registrable Shares, underwriter or controlling Person on the other, and each
party's relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission; provided, however, that, in any
such case, (A) no such holder, underwriter or controlling Person will be
required to contribute any amount in excess of the public offering price of
all such Registrable Shares offered by it pursuant to such registration
statement; and (B) no person or entity guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) will be entitled
to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.


5.06     Indemnification of Company.  
In the event that the Company registers any of the Registrable Shares under
the Securities Act, each holder of the Registrable Shares so registered will
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed or otherwise participated in the preparation of the
registration statement, each underwriter of the Registrable Shares so
registered (including any broker or dealer through whom such of the shares may
be sold) and each Person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act from and against any and all losses,
claims, damages, expenses or liabilities, joint or several, to which they or
any of them may become subject under the Securities Act, applicable state
securities laws or under any other statute or at common law or otherwise, and,
except as hereinafter provided, will reimburse the Company and each such
director, officer, underwriter or controlling Person for any legal or other
expenses reasonably incurred by them or any of them in connection with
investigating or defending any actions whether or not resulting in any
liability, insofar as such losses, claims, damages, expenses, liabilities or
actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement, in any
preliminary or amended preliminary prospectus or in the final prospectus (or
in the registration statement or prospectus as from time to time amended or
supplemented) or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary in order to make the statements therein not misleading, but only
insofar as any such statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company in connection
therewith by such holder of Registrable Shares expressly for use therein;
provided, however, that such holder's obligations hereunder shall be limited 

<PAGE>

to an amount equal to the proceeds received by such holder of Registrable
Shares sold in such registration.

Promptly after receipt of notice of the commencement of any action in respect
of which indemnity may be sought against such holder of Registrable Shares,
the Company will notify such holder of Registrable Shares in writing of the
commencement thereof (provided that failure to so notify such holder shall not
relieve such holder from any liability it may have hereunder), and such holder
of Registrable Shares shall, subject to the provisions hereinafter stated, be
entitled to assume the defense of such action (including the employment of
counsel, who shall be counsel reasonably satisfactory to the Company) and the
payment of expenses insofar as such action shall relate to the alleged
liability in respect of which indemnity may be sought against such holder of
Registrable Shares.  The Company and each such director, officer, underwriter
or controlling Person shall have the right to employ separate counsel in any
such action and to participate in the defense thereof, but the fees and
expenses of such counsel subsequent to any assumption of the defense by such
holder of Registrable Shares shall not be at the expense of such holder of
Registrable Shares unless employment of such counsel has been specifically
authorized in writing by such holder of Registrable Shares.  Such holder of
Registrable Shares shall not be liable to indemnify any Person for any
settlement of any such action effected without such holder's written consent.

In order to provide for just and equitable contribution to joint liability
under the Securities Act in any case in which the Company, any underwriter, or
any controlling Person or the Company or any underwriter, exercising its
rights under this Article V, makes a claim for indemnification pursuant to
this Section 5.06, but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding that this
Section 5.06 provides for indemnification, in such case, then, the Company,
underwriter or controlling Person, on the one hand, and such holder, on the
other hand, will contribute to the aggregate losses, claims, damages, expenses
or liabilities to which they may be subject (after contribution from others)
in such proportion as is appropriate to reflect the relative fault of the
Company, underwriter or controlling Person on the one hand and of the holder
of Registrable Shares on the other hand in connection with the statements or
omissions which resulted in such losses, claims, damages, expenses or
liabilities, as well as any other relevant equitable considerations.  The
relative fault of the Company, underwriter or controlling Person on the one
hand and of the holder of Registrable Shares on the other shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company, underwriter or
controlling Person on the one hand or by the holder of Registrable Shares on
the other, and each party's relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission; provided,
however, that, in any such case, (A) no such holder will be required to
contribute any amount in excess of the public offering price of all such
Registrable Shares offered by it pursuant to such registration statement; and
(B) no person or entity guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to
contribution from any person or entity who was not guilty of such fraudulent
misrepresentation.


5.07     Exchange Act Registration.  
The Company will use its best efforts to timely file with the Commission such
information as the Commission may require under either of Section 13 or
Section 15(d) of the Exchange Act; and the Company shall use its best efforts
to take all action as may be required as a condition to the availability of 

<PAGE>

Rule 144 or Rule 144A under the Securities Act (or any successor exemptive
rule hereinafter in effect) with respect to such Common Stock.  The Company
shall furnish to any holder of Registrable Shares forthwith upon request (i) a
written statement by the Company as to its compliance with the reporting
requirements of Rule 144, (ii) a copy of the most recent annual or quarterly
report of the Company as filed with the Commission, and (iii) such other
reports and documents as a holder may reasonably request in availing itself of
any rule or regulation of the Commission allowing a holder to sell any such
Registrable Securities without registration.  The Company shall use its best
efforts to facilitate and expedite transfers of the Common Shares pursuant to
Rule 144 under the Securities Act, which efforts shall include timely notice
to its transfer agent to expedite such transfers of Common Shares.


5.08     Damages.  
The Company acknowledges that the holder of Registrable Shares may not have an
adequate remedy if the Company fails to comply with this Article V and that
damages may not be readily ascertainable, and in the event of such failure,
the Company shall not oppose an application by the holder of Registrable
Shares or any other Person entitled to the benefits of this Article V
requiring specific performance of any and all provisions hereof or enjoining
the Company from continuing to commit any such breach of this Article V.


5.09     Further Obligations of the Company.  
Whenever under the preceding Section of this Article V, the Company is
required hereunder to register Registrable Shares, the Company shall also do
the following:

(a)  Furnish to each selling holder such copies of each preliminary and final
prospectus and such other documents as said holder may reasonably request to
facilitate the public offering of its Registrable Shares;

(b)  Use its best efforts to register or qualify the Registrable Shares
covered by said registration statement under the applicable securities or
"blue sky" laws of such jurisdictions as any selling holder may reasonably
request; provided, however, that the Company shall not be obligated to qualify
to do business in any jurisdictions where it is not then so qualified or to
take any action which would subject it to the service of process in suits
other than those arising out of the offer or sale of the securities covered by
the registration statement in any jurisdiction where it is not then so
subject;

(c)  Furnish to each selling holder a signed counterpart, addressed to the
selling holders, of

(i)  an opinion of counsel for the Company, dated the effective date of the
registration statement, and

(ii)  "comfort" letters signed by the Company's independent public accountants
who have examined and reported on the Company's financial statements included
in the registration statement, to the extent permitted by the standards of the
American Institute of Certified Public Accountants, covering substantially the
same matters with respect to the registration statement (and the prospectus
included therein) and (in the case of the accountants' "comfort" letters) with
respect to events subsequent to the date of the financial statements, as are
customarily covered in opinions of issuer's counsel and in accountants'
"comfort" letters delivered to the underwriters in underwritten public
offerings of securities, to the extent that the Company is required to deliver
or cause the delivery of such opinion or "comfort" letters to the underwriters
in an underwritten public offering of securities;


<PAGE>

(d)  Permit each selling holder of Registrable Shares or its counsel or other
representatives to inspect and copy such corporate documents and records as
may reasonably be requested by them;

(e)  Furnish to each selling holder of Registrable Shares a copy of all
documents filed with and all correspondence from or to the Commission in
connection with any such offering of securities;

(f)  Use its best efforts to facilitate the obtaining of all necessary
approvals from the National Association of Securities Dealers, Inc.; and

(g)  Otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earning statement covering the period of at
least 12 months, but not more than 18 months, beginning with the first month
after the effective date of the registration statement, which earning
statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder.

Whenever under the preceding Sections of this Article V the holders of
Registrable Shares are registering such shares pursuant to any registration
statement, each such holder shall timely provide to the Company, at its
request, such information and materials as it may reasonably request in order
to effect the registration of such Registrable Shares.


5.10     Expenses.  
In the case of each registration effected under Section 5.01, 5.02 or 5.03,
the Company shall bear all reasonable costs and expenses of each such
registration on behalf of the selling holders of Registrable Shares,
including, but not limited to, the Company's printing, legal and accounting
fees and expenses, Commission and NASD filing fees, "Blue Sky" fees and
expenses and the reasonable fees and disbursements of one counsel for the
selling holders of Registrable Shares in connection with the registration of
their Registrable Shares; provided, however, that the Company shall have no
obligation to pay or otherwise bear any portion of the underwriters'
commissions or discounts attributable to the Registrable Shares being offered
and sold by the holders of the Registrable Shares, or the fees and expenses of
more than one counsel for the selling holders of Registrable Shares in
connection with the registration of the Registrable Shares.  The Company shall
pay all expenses of the holders of the Registrable Shares in connection with
any registration initiated pursuant to this Article V which is withdrawn,
delayed or abandoned at the request of the Company, unless such withdrawal,
delay or abandonment is caused by the fraud, material misstatement or omission
of a material fact by a holder of Registrable Shares to be included in such
registration.


5.11     Approval of Underwriter.  
Any managing underwriter engaged in any registration made pursuant to Section
5.02 shall be a nationally recognized firm requiring the approval in writing
of the holders of a majority of the Registrable Shares requesting such
registration and the consent of the Company, which consent shall not be
unreasonably withheld or delayed.

5.12     Transferability.  
For all purposes of Article V of this Agreement, the holder of Registrable
Shares shall include not only the Purchaser but (i) any assignee or transferee
of the Registrable Shares who acquires at least 10% of the Registrable Shares
purchased by the Purchaser on the date hereof and who is not a competitor of
the Company, or (ii) any general or limited partner or any officer or director
of any such Person or their affiliates, including, but not limited to, their 

<PAGE>

immediate family, irrevocable trusts for estate planning purposes and personal
representatives; provided, however, that such assignee or transferee agrees in
writing to be bound by all of the provisions of this Agreement.


5.13     Mergers, Etc.  
The Company shall not, directly or indirectly, enter into any merger,
consolidation or reorganization in which the Company shall not be the
surviving corporation unless the proposed surviving corporation shall, prior
to such merger, consolidation or reorganization, agree in writing to assume
the obligations of the Company under Article V of this Agreement, and for that
purpose references hereunder to Registrable Shares shall be deemed to be
references to the securities which the holders of Registrable Shares would be
entitled to receive in exchange for Registrable Shares under any such merger,
consolidation or reorganization; provided, however, that the provisions of
this Section 5.13 shall not apply in the event of any merger, consolidation,
or reorganization in which the Company is not the surviving corporation if all
stockholders are entitled to receive in exchange for their Registrable Shares
consideration consisting solely of (i) cash, (ii) securities of the acquiring
corporation which may be immediately sold to the public without registration
under the Securities Act, or (iii) securities of the acquiring corporation
which the acquiring corporation has agreed to register within 90 days of
completion of the transaction for resale to the public pursuant to the
Securities Act.


5.14     Limitations on Subsequent Registration Rights.  
From and after the date of this Agreement, the Company shall not, without the
prior written consent of the holders of at least a majority of the Registrable
Securities, enter into any agreement with any holder or prospective holder of
any securities of the Company which would allow such holder or prospective
holder of any securities of the Company the right to require the Company to
initiate any registration of any securities of the Company.  Any right given
by the Company to any holder or prospective holder of the Company's securities
in connection with the registration of securities shall be conditioned such
that it shall be consistent with the provisions of this Article V and with the
rights of the holder provided in this Agreement.  This Article V shall not
limit the right of the Company to enter into any agreements with any holder or
prospective holder of any securities of the Company giving such holder or
prospective holder the right to require the Company, upon any registration of
any of its securities, to include, among the securities which the Company is
then registering, securities owned by such holder if such rights are
subordinate to the rights of a holder of Registrable Securities.



ARTICLE VI:  RIGHT OF FIRST REFUSAL

6.01     Right of First Refusal.  
Except as set forth in Section 6.06, before the Company shall issue, sell or
exchange, agree or obligate itself to issue, sell or exchange, or reserve or
set aside for issuance, sale or exchange, any (i) shares of Common Stock, (ii)
any other equity security of the Company, including without limitation, shares
of Preferred Stock, (iii) any convertible debt security of the Company,
including without limitation, any debt security which by its terms is
convertible into or exchangeable for any equity security of the Company, (iv)
any security of the Company that is a combination of debt and equity, or (v)
any option, warrant or other right to subscribe for, purchase or otherwise
acquire any such equity security or any such debt security of the Company, the
Company shall, in each case, first offer to sell such securities (the "Offered
Securities") to the Purchaser at a price and on such other terms as shall have
been specified by the Company in writing delivered to the Purchaser (the 

<PAGE>

"Offer"), which Offer by its terms shall remain open and irrevocable for a
period of 30 days from receipt of the Offer.


6.02     Notice of Acceptance.  
Notice of the Purchaser's intention to accept, in whole or in part, any Offer
made pursuant to Section 6.01 shall be evidenced by a writing signed by the
Purchaser and delivered to the Company prior to the end of the 30-day period
of such offer, setting forth the number of Offered Securities the Purchaser
elects to purchase (the "Notice of Acceptance").


6.03     Conditions to Acceptances and Purchase.  

(a)  Permitted Sales of Refused Securities.  
In the event that a Notice of Acceptance is not given by the Purchaser in
respect of all the Offered Securities, the Company shall have 90 days from the
end of said 30-day period to sell any such Offered Securities as to which a
Notice of Acceptance has not been given by the Purchaser (the "Refused
Securities") to the Person or Persons specified in the Offer, but only for
cash and otherwise in all respects upon terms and conditions, including,
without limitation, unit price and interest rates, which are no more
favorable, in the aggregate, to such other Person or Persons or less favorable
to the Company than those set forth in the Offer.

(b)  Reduction in Amount of Offered Securities.  
In the event the Company shall propose to sell less than all of the Refused
Securities (any such sale to be in the manner and on the terms specified in
Section 6.03(a) above), then the Purchaser may reduce the number of shares or
other units of the Offered Securities specified in its Notice of Acceptance to
an amount which shall be not less than the amount of the Offered Securities
which the Purchaser elected to purchase pursuant to Section 6.02 multiplied by
a fraction, (i) the numerator of which shall be the amount of Offered
Securities that the Company actually proposes to sell, and (ii) the
denominator of which shall be the amount of all Offered Securities. In the
event that the Purchaser so elects to reduce the number or amount of Offered
Securities specified in its Notice of Acceptance, the Company may not sell or
otherwise dispose of more than the reduced amount of the Offered Securities
until such securities have again been offered to the Purchaser in accordance
with Section 6.01.

(c)  Closing.  
Upon the closing, which shall include full payment to the Company, of the sale
to such other Person or Persons of all or less than all the Refused
Securities, the Purchaser shall purchase from the Company, and the Company
shall sell to the Purchaser, the number of Offered Securities specified in the
Notice of Acceptance, as reduced pursuant to Section 6.03(b) if the Purchaser
has so elected, upon the terms and conditions specified in the Offer.  The
purchase by the Purchaser of any Offered Securities is subject in all cases to
the preparation, execution and delivery by the Company and the Purchaser of a
purchase agreement relating to such Offered Securities reasonably satisfactory
in form and substance to the Purchaser and its counsel.


6.04  Further Sale.  
In each case, any Offered Securities not purchased by the Purchaser or other
Person or Persons in accordance with Section 6.03 may not be sold or otherwise
disposed of until they are again offered to the Purchaser under the procedures
specified in Sections 6.01, 6.02 and 6.03.




<PAGE>

6.05  Termination and Waiver of Right of First Refusal.  
The rights of the Purchaser under this Article VI may be waived only upon the
prior written consent of the Purchaser and shall terminate when the Purchaser
owns less than ten percent of the Common Shares.


6.06  Exceptions.  
The rights of the Purchaser under this Article VI shall not apply to:

(a)  Common Stock issued as a stock dividend to holders of Common Stock or
upon any subdivision or combination of shares of Common Stock;

(b)  Preferred Stock issued as a dividend to holders of Preferred Stock upon
any subdivision or combination of shares of Preferred Stock;

(c)  up to 3,576,666 shares of Common Stock issued upon the exercise of
outstanding stock options and warrants;

non-qualified stock option plan or agreement, employee stock ownership plan,
employee benefit plan, stock purchase agreement, stock plan, stock restriction
agreement, consulting agreement or other option, arrangement, agreement or
plan approved by two-thirds of the members of the Compensation Committee
(including the Investor Directors on such Committee, if any), or if there is

the Company (including the Investor Directors);

(e)  securities issued upon conversion of convertible securities described in
Exhibit 3.17; and

(f)  the Warrant Shares upon the exercise of the Warrants.

Each of the foregoing numbers shall be subject to equitable adjustment in the

8.11     Dispute Resolution. 

(a)  Good-Faith Negotiations.  
If any dispute arises under this Agreement that is not settled promptly in the
ordinary course of business, the parties shall seek to resolve any such
dispute between them, first, by negotiating promptly with each other in good
faith in face-to-face negotiations.  These face-to-face negotiations shall be
conducted by the respective designated senior management representative of
each party.  If the parties are unable to resolve the dispute between them
through these face-to-face negotiations within 20 days (or such period as the
parties shall otherwise agree) following the date of notification (the "Notice
Date") by one party to the other of the existence of such dispute, then any
such disputes shall be resolved in the following manner.

(b)  Mediation. 
The parties shall endeavor to resolve any dispute arising out of or relating
to this Agreement by mediation under the CPR Mediation Procedures for Business
Disputes.  Unless otherwise agreed, the parties will select a mediator from
the CPR Panels of Neutrals and shall notify CPR to initiate the selection
process.

(c)  Resolution of Disputes.  

(i)  Any action, suit or proceeding where the amount in controversy as to at
least one party, exclusive of interest and costs, exceeds $1,000,000 ("Summary
Proceeding"), arising out of or relating to this Agreement or any other
agreement executed in connection herewith or the breach, termination or
validity thereof which has not been resolved by mediation as provided herein
within 90 days of the Notice Date, shall be litigated exclusively in the
Superior Court of the State of Delaware (the "Delaware Superior Court") as a
summary proceeding pursuant to Rules 124-131 of the Delaware Superior Court,
or any successor rules (the "Summary Proceeding Rules").  Each of the parties
hereto hereby irrevocably and unconditionally (A) submits to the jurisdiction
of the Delaware Superior Court for any Summary Proceeding, (B) agrees not to
commence any Summary Proceeding except in the Delaware Superior Court, (C)
waives, and agrees not to plead or to make, any objection to the venue of any
Summary Proceeding in the Delaware Superior Court, (D) waives, and agrees not

inconvenient forum, (E) waives, and agrees not to plead or to make, any claim
that the Delaware Superior Court lacks personal jurisdiction over it, (F)
waives its right to remove any Summary Proceeding to the federal courts except
where such courts are vested with sole and exclusive jurisdiction by statute
and (G) understands and agrees that it shall not seek a jury trial or punitive

<PAGE>

damages in any Summary Proceeding based upon or arising out of or otherwise
related to this Agreement or any other agreement executed in connection
herewith or the breach, termination or validity thereof, and waives any and
all rights to any such jury trial or to seek punitive damages.

(ii)  In the event any action, suit or proceeding where the amount in
controversy as to at least one party, exclusive of interest and costs, does
not exceed $1,000,000 (a "Proceeding"), arising out of or relating to this
Agreement, or any other agreement executed in connection herewith or the
breach, termination or validity thereof is brought, the parties to such
Proceeding agree to make application to the Delaware Superior Court to proceed
under the Summary Proceeding Rules.  Until such time as such application is
rejected, such Proceeding shall be treated as a Summary Proceeding and all of
the foregoing provisions of this Section relating to Summary Proceedings shall
apply to such Proceeding.

(iii)  If a Summary Proceeding is not available to resolve any dispute
hereunder, the controversy or claim shall be settled by arbitration conducted
on a confidential basis, under the U.S. Arbitration Act, if applicable, and
the then current Commercial Arbitration Rules of the American Arbitration
Association (the "Association") strictly in accordance with the terms of this
Agreement and the substantive law of the State of Delaware, including such law
in respect of the statute of limitations.  The arbitration shall be conducted
at the Association's regional office located closest to the Company's
principal place of business by three arbitrators at least one of whom shall be
knowledgeable in AM/FM technology, programming and implementation, one of whom
shall be an attorney and one of whom shall be a member of a "Big Six"
accounting firm. The arbitrators are not empowered to award damages in excess
of compensatory damages and each party hereby irrevocably waives any right to
recover such damages with respect to any such disputes.  Judgment upon the
arbitrators' aware may be entered and enforced in any court of competent
jurisdiction.

(d)  Neither party shall be precluded hereby from securing equitable remedies
in courts of any jurisdiction, including, but not limited to, temporary
restraining orders and preliminary injunctions to protect its rights and
interests but shall not be sought as a means to avoid or stay arbitration or
Summary Proceeding.

(e)  Each party is required to continue to perform its obligations under this
contract pending final resolution of any dispute arising out of or relating to
this contract, unless to do so would be impossible or impracticable under the
circumstances.

instituting the action, or, if the parties elect to share costs instituting
and maintaining such action, such costs and expenses shall be borne by the
parties in such proportions as they may agree in writing.  3D shall be
entitled to counsel in such proceedings at its own expense as necessary or
appropriate.  Each party shall execute all necessary and proper documents and
take such action as shall be appropriate to allow the other party to institute
and prosecute such infringement actions.  Any award paid by third parties as a
result of such an infringement action (whether by way of settlement or
otherwise), shall be paid to the party who instituted and maintained such
action, or, if  both parties instituted  and maintained such action, such
award shall be allocated among the parties in proportion to their respective
contributions to the costs and expenses incurred in such action.
